Sarah Ferguson took her daughters, Beatrice, 20, and Eugenie, 18, to watch the final of the Gold Cup Polo at the Santa Maria polo club in Sotogrande, Spain over the weekend.

Beatrice's boyfriend Dave Clark, who works for Richard Branson's Virgin Galactic Group, was invited to join them on holiday proving that he has got the parental thumbs up.

Clark looked completely at ease in the company of Beatrice's loved ones, laughing and joking the group as they watched on from the sands.

The party was also joined by a mystery male, prompting speculation he may have been Eugenie's companion for the day.

Prince Andrew is also said to approve of his daughter's relationship with Dave, who lives with his family in their £5million mansion in North London.

The group are holidaying together to celebrate Eugenie's A-level results and Beatrice's recent 20th birthday.

The break may be the last time the three are together for a while.

Eugenie is expected to soon head off on her gap year abroad while Bea is gearing up to start a degree at Goldsmiths College in London next month.

Hands on: Princess Beatrice leans in for a hug
